  2. Half-reaction - Wikipedia

    en.wikipedia.org/wiki/Half-reaction

    For oxidation-reduction reactions in acidic conditions, after balancing the atoms and oxidation numbers, one will need to add H + ions to balance the hydrogen ions in the half reaction. For oxidation-reduction reactions in basic conditions, after balancing the atoms and oxidation numbers, first treat it as an acidic solution and then add OH − ...

    References and notes CH 3 COOH + 2H + + 2e − → CH 3 CHO + H 2 O: −0.58 Many carboxylic acid: aldehyde redox reactions have a potential near this value 2 H + + 2 e − → H 2: −0.41 Non-zero value for the hydrogen potential because at pH = 7, [H +] = 10 −7 M and not 1 M as in the standard hydrogen electrode (SHE), and that: E red = -0 ...

  4. Redox - Wikipedia

    en.wikipedia.org/wiki/Redox

    Redox (/ ˈ r ɛ d ɒ k s / RED-oks, / ˈ r iː d ɒ k s / REE-doks, reduction–oxidation [2] or oxidation–reduction [3]: 150 ) is a type of chemical reaction in which the oxidation states of the reactants change. [4] Oxidation is the loss of electrons or an increase in the oxidation state, while reduction is the gain of electrons or a ...

  5. Organic redox reaction - Wikipedia

    en.wikipedia.org/wiki/Organic_redox_reaction

    Organic redox reactions: the Birch reduction. Organic reductions or organic oxidations or organic redox reactions are redox reactions that take place with organic compounds.In organic chemistry oxidations and reductions are different from ordinary redox reactions, because many reactions carry the name but do not actually involve electron transfer. [1]

  6. Nernst equation - Wikipedia

    en.wikipedia.org/wiki/Nernst_equation

    In electrochemistry, the Nernst equation is a chemical thermodynamical relationship that permits the calculation of the reduction potential of a reaction (half-cell or full cell reaction) from the standard electrode potential, absolute temperature, the number of electrons involved in the redox reaction, and activities (often approximated by concentrations) of the chemical species undergoing ...

  7. Reducing agent - Wikipedia

    en.wikipedia.org/wiki/Reducing_agent

    An agent's oxidation state describes its degree of loss of electrons, where the higher the oxidation state then the fewer electrons it has. So initially, prior to the reaction, a reducing agent is typically in one of its lower possible oxidation states; its oxidation state increases during the reaction while that of the oxidizer decreases.

  8. Fenton's reagent - Wikipedia

    en.wikipedia.org/wiki/Fenton's_reagent

    Oxidation of an organic compound by Fenton's reagent is rapid and exothermic and results in the oxidation of contaminants to primarily carbon dioxide and water. Reaction was suggested by Haber and Weiss in the 1930s as part of what would become the Haber–Weiss reaction. [7] Iron(II) sulfate is typically used as the iron catalyst.

  9. Oxidation state - Wikipedia

    en.wikipedia.org/wiki/Oxidation_state

    The increase in the oxidation state of an atom, through a chemical reaction, is known as oxidation; a decrease in oxidation state is known as a reduction. Such reactions involve the formal transfer of electrons: a net gain in electrons being a reduction, and a net loss of electrons being oxidation.
